Ruthenium Reverb

[gul]

Felix Kalium (a.k.a. m-kresol on the Madbean forum) has a really cool project called Ruthenium Reverb. I purchased the OSH Park boards, and it seems there's a manufacturing error on them. I built up all three, went back and forth with Felix trying to troubleshoot, and I think we just came to the conclusion that something went amiss with the boards. Anyway, I would love to get a vero layout for this if anyone has time. Here is the link to Felix's nice build doc:

Thanks in advance to everyone at TagboardFX for all the help and wonderful layouts!

Here you go loe,

Let me know how it goes.

06/03 Corrected Input pulldown resistor

Thanks, man! You're on fire lately with these layouts. Much appreciated. I'll be working on this tomorrow. I'll let you know how it goes. I sure would love to get this reverb working once and for all.

Thanks loe!

I'm laid up with a broken leg, can't get to my workbench in the basement so I thought I'd help out with layouts in the meantime.

Let me know how it goes, it will make my day if it works out well.

I couldn't even wait til morning, lol. I built the circuit last night. I have to say, it's really well laid out. It was a pleasure to put together. I'll finish it up today and report back. Thanks again.

Way to make good use of your healing time, aside from healing!

Thanks again loe, I hope it fires up without issue.

... And it does! Hahaha. I knew I wasn't crazy. Worked right away, no issues whatsoever.

This thing has pretty quiet output... Well, the reverb is itself is pretty noisy, even with shielded cable all around. But the output signal is far quieter than when bypassed, so I'm going to throw a boost in the box with it. I'll be sure to add photos soon.

MAO, thanks again. I very much appreciate the generosity of your time!

loe, I spotted an error.

The input pulldown resistor was marked as 1k, should be 1M. That would explain the volume drop for sure!

I updated the layout.

[gul]

Wow, thanks for catching that. I made that change, shortened the wires to and from the tank, and it's now perfect. What a cool little reverb.

Thanks for the layout! Just built one last night and it sounds so good! I missed a good spring reverb sound, so I built this for my amp. Going to hook it up to the effects loop and tuck it away inside the head.

I did notice that having a footswitch on this "pedal" will be really noisy because of the springs bouncing around inside. Might be a good idea to use a soft touch switch, but even then you'd have to lightly engage it haha

Is there a schematic still available for this? I couldnt find it on the googles..

Check the link to the build doc in the original post by loe.

Ha! Link didn't work @ work :D Thanks!

Hello, Just wanting to know whether the accutronics AMC2EF2 reverb tank would work??

The AMC2BF2 seems out of stock in numerous places.

Here are some details from Banzai.

Accutronics AMC2EF2, made in Korea. Medium Decay time.

Specifications:
Input / DC Resistance: 600 / 80 Ohm
Output / DC resistance: 1500 Ohm / 218 Ohm
Decay: 1,75 - 2,5 sec.
Springs: 2
Lenth: 13,5 cm
Width: 38 cm
Height: 3,2 cm


Cheers!

I have tried the “E” since someone sent me one by accident, and it doesn’t work very well. If you have that tank you can build the Stage Center Reverb which I created a layout that I verified myself. FYI, it sounds a lot better running +\- 18v and some I used a voltage doubler/inverter that was posted by Mark a while back. It works fine on +\- 9, but it’s not as clean.

Thanks for your response.. I’ve found the right tank for the ruthenium so hopefully it all works out as it should!
